Question

dry pellets of a base X when kept in open absorb moisture and turn sticky. the compound is also formed by chloro alkali process. write chemical name and formula of x

Answer 1

X is Sodium Hydroxide.
Sodium hydroxide - NaOH

Answer 2

X is sodium hydroxide which is represented as NaOH.

EXPLANATION:

Sodium hydroxide is a base that reacts with the air and absorbs water.  When left in open, NaOH absorbs the moisture and forms a sticky substance. On reaction with air, NaOH forms sodium carbonate which is a salt and the sticky substance.  This reaction is called as the neutralization reaction.

The chemical equation for the chemical reaction is as follows:

$\mathrm{NaOH}+\mathrm{CO}_{2} \rightarrow \mathrm{Na}_{2} \mathrm{CO}_{3}+\mathrm{H}_{2} \mathrm{O}$
